Discussion Slim-looking dabbling duck with a proportionately long bill, recalling that of Northern Shoveler. Sexes are dissimilar: male's plumage color is unmistakable; female is superficially similar to female Blue-winged Teal, but distinguishable by bill length, uniformly brown head, and association with male. Both sexes show pale underwings in flight and upper-wing markings similar to those of Blue-winged: pale blue panel, white wedge, and greenish speculum. Not particularly gregarious.
